Fluval G3 Pre-Filter Cartridge

You'll need some extras of these because they get dirty fast. These little buggers are $25 at local stores so I wanted a couple extra. Take my advice and buy some wire brushes to clean them because the crevices on them are so small you can't clean them without one. It took me a while to figure out what I could use to clean these because to me it's an awesome filter but they proprietary filter elements are a horrible design. They should make a sleeve style filter cartridge like on the Old school magnum 350. The top little areas of this filter element are horrible to try to clean. I've only had this filter for a couple weeks

I love my Fluval G3 filter for my Cichlids but they're messy and the filters don't last long between cleanings, needed back up replacements. These are PERFECT and cut down the time to switch out the filters by having the replacements, just rinse them and run the brush through a few times then soak them in white distilled vinegar overnight. Rinse and let dry DONE! Highly Recommend

Finally replaced my 25 year old filter system with the Fluval G3. Wow! what an improvement. Now have consistently clear water. The aquarium's rear glass, even after previously scrapping and scrubbing, was still covered with "stuff", now has mostly been self cleaned. It is very easy to maintain, I can swap filters without dealing with closing and opening valves along with the occasional water leakage that was necessary with my old magnum 350.Even the fish seem to be happier!

Good product

nice to find factory parts on Amazon!good filter for the G3

I ordered one of these 2 weeks ago and it was a white pre-filter with a gray bottom. It had a plastic filter media and it works great, 4 or 5 stars. I wanted to get a couple more so I ordered 2 more just 2 weeks later and I got the white pre-filter with the black bottom and it has a fabric like filter media and while it works ok, it doesn't last long, clogs easier and is hard to clean, very hard. Even with the cleaning brush, they never really get clean. I'm not returning them this time because I need them, but I'm going to order again to get the plastic media, which hagen tells me are newer, and if I don't get them, they will be returned until I do get them. I wish this item had a different box or something because you can't tell the difference between old and new product from the pictures. buyer beware on this item.

This is a great filter. It is easy to change and clean. I am shocked at how much debris is trapped in this filter each time I have to do the scheduled cleaning. I keep two on hand and swap them out to prolong the use of the filters.

This replaced the original that had developed a hole somehow. Works just as well.
